For meaningful interaction between a robot and a human, an autonomous robot must recognize whether the experienced situation is created by people or by the environment. Using only proprioceptive data from a mobile robotic platform, we discover that it is possible to distinguish sensory data patterns involving interaction. These patterns are obtained whilst navigating varying environments, both human populated and unpopulated. The paper reports the initial set of trials using Roball, a spherical mobile robot. Also described is the experimental methodology currently followed to validate the hypothesis that child interaction can be perceived directly from navigation sensors onboard a robotic platform.

Journal of robotics and Mechatronics 1997年第2期9卷 146-151页

The emergence and effectiveness of communication interface in a colony of autonomous agents is discussed in this paper. The robotic agents sense the world within which they are embedded, while performing specific tasks in the world. Some of the tasks require the simultaneous cooperation of two robotic agents. These agents are able to sense other agents and communicate via simple, task-related messages. Using genetic algorithms, a colony of agents is evolved, producing agents with improved performance. It is shown that the tendency of the robotics agents to communicate increases through evolution, as the colony cooperates more, in order to perform more tasks. The concepts developed through computer simulation are tested for feasibility in a team of four small mobile-manipulator robots, each controlled autonomously via an on-board micro-processor. © Fuji Technology Press Ltd.

Recent advances in topological quantum materials have spurred significant interest in exploring superconductors that also host nontrivial band topology, as these materials can serve as platforms for novel electronic phases and quantum technologies. TlTaSe 2 is one such non-centrosymmetric, quasi-two-dimensional semimetal with nodal-line topological features protected by mirror-reflection symmetry. In this study, we theoretically predict its superconducting properties using first-principles anisotropic Migdal–Eliashberg theory. Our results indicate that the states at the Fermi, are primarily Ta 5d and Tl 6p orbitals. Thus, exhibiting a multiband electronic structure. Notably, from our calculations, we find two distinct superconducting gaps of 2.15 meV and 4.5 meV on different Fermi surface sheets, arising from strongly anisotropic electron-phonon interactions predominantly involving in-plane vibrations of the Ta and Tl atoms. Using the Allen–Dynes-modified McMillan formula with a Coulomb pseudopotential μ* = 0.16, we predict a superconducting transition temperature Tc of 6.67 K. These findings underscore the significance of TlTaSe 2 as a candidate for topological superconductivity and provide insights into how the interplay between anisotropy, electron-phonon coupling, and nontrivial band topology can be explored for quantum computing and spintronics applications.

Continuum robots or serpentine manipulators have dexterous bodies that fit in narrow space and have advantages over traditional robot arms. In this paper, universal joints were involved in our serpentine manipulator to reinforce its stiffness. In order to have a more compact physical body without compensating much of the dexterity, the manipulator should be under-actuated. For mechanical errors, assembly errors and deformation of components, it is not likely to design the full kinematics model. Also for cable-driven manipulator, the actuation of the driven- cables are always highly coupled. In this paper, we proposed a CNN-based control method to learn the actual kinematics of the manipulator by introducing an ideal model mapping from the cable actuation to joint space. In such manner, we can achieve self-learnt kinematics model with reduced risk of damage in cable.

Bio-syncretic robots, consisting of living biological materials and traditional electromechanical systems, have attracted lots of attention due to the potentialities of self-sensing, self-actuation and self-repairing with intrinsic safety and high energy conversion efficiency. However, most of current researches focus on the movement of the devices, and have ignored the study on the control of actuation unit “cells”, which is as important as motors for traditional electromechanical robots. In this work, the effects of cell culturing time, seeding concentration and functional drugs (cytochalasin and adrenalin) on contractile frequency and force strength of cardiomyocytes have been studied using scanning ion conductance microscope (SICM) and arrays of micro-pillars made of PDMS. This work will lay the foundation for the further study of quantitatively control of bio-syncretic robots actuated by cardiomyocytes and is also meaningful for the development of cytology, medicine, and clinical science.

In this paper, a position-based visual servo method is proposed to perform the high-accuracy precision grasping and collaborative tasks for dual arm robot. Firstly, an adaptive color identification procedure is presented to cope with the problem that the color of the object will change when the object is in different positions for object identification. Secondly, we employ the position-based visual servo method to build a control loop including the sensor data streams obtained from the visual system, the force / torque sensors and the joint encoders. Based on these data, the joint velocity value and the on-line motion trajectory of manipulator could be obtained, which led to a good performance on grasping a fixed object and tracking online. Finally, we implement three experiments to verify the effectiveness of the position-based visual servo method in this paper. The experimental results demonstrate the proposed method can effectively identify target objects with a good positioning accuracy and high capture success rate for collaborative tasks.

Underwater Target Positioning with a Single Acoustic Sensor

The availability of reliable underwater positioning systems to localize one or more vehicles simultaneously based on information received on-board a support ship or an autonomous surface vessel is key to the operation of some classes of AUVs. Furthermore, there is considerable interest in reducing the number of sensors involved in acoustic navigation/positioning systems to reduce the costs involved and the time consumed in the deployment, callibration, and recovery phases. Motivated by these considerations, in this paper we address the problem of single underwater target positioning based on measurements of the ranges between the target and a moving sensor at the sea surface, obtained via acoustic ranging devices. In particular, and speaking in loose terms, we are interested in determining the optimal geometric trajectory of the surface sensor that will, in a well defined sense, maximize the range-related information available for underwater target positioning. To this effect, an appropriate Fisher Information Matrix is defined and its determinant is maximized to yield the sensor trajectory that maximizes the accuracy of the target position estimate that can possibly be obtained with any unbiased estimator. It is shown that the optimal trajectory depends on the relative velocity of the sensor, the sampling time between measurements, and the number of measurements acquired for the FIM computation. Simulation examples illustrate the key results derived.

This paper addresses the problem of Fault Detection and Isolation (FDI) for navigation systems equipped with sensors providing inertial measurements and vector observations. Two strategies are proposed. The first one takes advantage of existing hardware redundancy, providing sufficient conditions for the isolation of faults. The second approach exploits the analytical redundancy between the angular velocity measurements and the vector observations, by resorting to Set-Valued Observers (SVOs). The behavior of both strategies are illustrated in simulation.

Optimal Sensor Trajectories for Mobile Underwater Target Positioning with Noisy Range Measurements

引用

IFAC Proceedings Volumes 2014年第3期47卷 5139-5144页

There is considerable interest in reducing the number of sensors/beacons involved in underwater positioning/navigation systems since this has the potential to drastically reduce the costs and the time spent in deploying, calibrating, and recovering acoustic equipment at sea. Motivated by these considerations, we address the problem of single underwater target positioning based on acoustic range measurements between the target and a moving sensor at the sea surface. In particular, the goal of the present work is to compute optimal geometric trajectories for the surface sensor that will, in a well defined sense, maximize the range-related information available for underwater target positioning and tracking. To this effect, the Fisher Information Matrix and the maximization of its determinant are used to determine the sensor trajectory that yields the most accurate positioning of the target, while the latter describes a preplanned trajectory. It is shown that the optimal trajectory depends on the velocity of the sensor, the velocity and trajectory of the target, the sampling time between measurements, the measurement error model, and the number of measurements used to compute the FIM. Simulation examples illustrate the key results derived.
